Suture Anchor With One-Way Valve for Endoscopic Deployment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current surgical procedures require re-suturing a wound or incision to secure suture anchors after the initial stitching, which is inefficient and unnecessary, as existing methods do not allow for the deployment of suture anchors into already placed sutures.
Innovation Solution
A suture anchor with a one-way valve and a deployment device that allows for the secure attachment of a suture anchor to a section of suture already in place within the patient's tissue, using a hollow member with a slot and a one-way valve to prevent suture exit and a launch bar mechanism for easy deployment through an endoscope.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional suturing techniques are used to secure suture anchors after initial stitching, then the suture anchors can be secured in tissue, but the procedure requires re-suturing which reduces surgical efficiency and increases tissue trauma
Solution Approach 1:
The suture anchor device allows the existing suture to serve itself by capturing and securing the anchor through its own passage through the tissue. The suture that was already placed performs the dual function of both closing the wound and securing the anchor, eliminating the need for separate re-suturing operations.
Solution Approach 2:
The suture is placed through the tissue in advance before the anchor is applied. This preliminary suture placement creates a pre-formed pathway that the anchor can subsequently engage and secure, allowing the anchor to be attached to the existing suture rather than requiring new suturing after anchor placement.
2Reliability
If conventional suturing techniques are used to secure suture anchors after initial stitching, then the suture anchors can be secured in tissue, but the procedure requires additional surgical steps which increases complexity
Solution Approach 1:
The invention merges the functions of wound closure and anchor securing into a single integrated process. The existing suture that closes the wound is simultaneously used to secure the anchor, combining two separate surgical objectives into one unified procedure that reduces overall complexity.
Solution Approach 2:
The suture serves multiple functions: it closes the wound/incision and simultaneously secures the suture anchor to the tissue. This multi-functional use of the same suture eliminates the need for separate suturing operations and simplifies the overall surgical procedure.
3Reliability
If conventional suturing techniques are used to secure suture anchors after initial stitching, then the suture anchors can be secured in tissue, but it requires additional surgical intervention which increases tissue trauma
Solution Approach 1:
The existing suture that is already in place performs the dual function of wound closure and anchor securing. By utilizing the suture's own pathway through the tissue, the system avoids additional incisions or punctures that would cause further tissue trauma.
Solution Approach 2:
The suture is placed through the tissue in advance during the initial wound closure. This preliminary action creates a pre-formed pathway that the anchor can subsequently engage, eliminating the need for additional surgical intervention that would cause further tissue damage.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
Enables the secure anchoring of sutures without re-suturing, facilitating minimally invasive procedures by allowing for the attachment of suture anchors to existing sutures, thereby enhancing surgical efficiency and reducing tissue trauma.
Implementation Method 1
a one-way valve positioned within the enclosure at the slot to allow entry of a suture through the opening into the enclosure and to prevent the exit of the suture from the enclosure
Implementation Method 2
Several known anchors rely upon mechanical interlocks between the body tissue and the anchor to retain the anchor in place against the influence of forces transmitted through the suture to the anchor

AI summary
A suture anchor is provided which includes a hollow member having an outer surface defining an enclosure, the member having a longitudinal axis and a slot through a portion of the outer surface in a direction transverse to the longitudinal axis, the slot providing an opening into the enclosure. The suture anchor further includes a one-way valve positioned within the enclosure at the slot to allow entry of a suture through the slot into the enclosure and to prevent the exit of the suture from the enclosure. A device is provided for deploying the suture anchor. The deployment device includes an elongate hollow member having a suture anchor release zone positioned at the distal end, a launch bar having at least a portion positioned in the release zone. The launch bar is movable within the release zone between a resting position and a launching position and is operatively connected to an actuation member positioned proximally to the elongate member. The hollow elongate member defines a housing for receiving a plurality of suture anchors in tandem.
